Description

[Detailed Description of the Invention] The present invention relates to a double bag for fruits to protect fruits from pests and sunburn, and particularly to the structure of the inner bag.

In conventional double bags for fruit, the edges of the outer bag and inner bag are manufactured to have the same shape and almost the same dimensions, and the outer and inner bags overlap completely at the edges, so there is no hanging When working on
The problem was that the paper around the mouth became thicker and harder, making it difficult to work with.

In order to deal with this, a synthetic resin foam sheet is polymerized so that the eye ends of the paper bag remain on the inner periphery of the paper bag, and the paper bag and the foam sheet are bonded at least at required points on the mouth side to double the paper bag. A protective cover for fruits with a structure was developed in 1972.
-164947.

However, since the total length of the internal synthetic resin foam sheet is shorter than the total length of the external paper bag, if the internal synthetic resin foam sheet and paper bag are not bonded together within the external paper bag, the internal The synthetic resin foam sheet moved, making it impossible to stably attach it, and adhering it was troublesome.

The present invention eliminates the above-mentioned drawbacks, eliminates the movement of the inner bag within the outer bag even if the outer bag and inner bag are not glued together, and reduces the paper thickness at the edge of the outer bag to improve the efficiency of pinning work. The object of the present invention is to provide a double bag for fruit which is designed to improve the quality of the product.

In order to achieve this purpose, the double bag for fruit of the present invention is
It consists of an inner bag 1 and an outer bag 4, which have approximately the same overall length and width, and when the inner bag 1 is stored inside the outer bag 4, the portion where the lip of the inner bag 1 is located at the mouth edge 8 of the outer bag 4. 9 and a portion 10 located further inside the bag than the mouth edge 8 of the outer bag 4, and the bottom edge of the inner bag 1 is formed parallel to the mouth edge of the inner bag 1. .

Embodiments of the present invention will be described based on the drawings.

Figures 1 to 5 show examples of the inner bag in the double bag for fruit according to the present invention, and the total length and width of each of these inner bags 1 are almost the same as that of the outer bag 4 shown in Figure 6. It has the dimensions of

In FIG. 1, the rim of the inner bag 1 is cut into a convex semicircular shape, and when the inner bag 1 is stored in the outer bag 4, a portion 9 located at the rim 8 of the outer bag 4 and the outer bag 4 The part 1 that is inside the bag from the rim 8 of
0, while the bottom edge is cut into a quarter circle parallel to the convex semicircle of the mouth edge.

In addition, it goes without saying that the inner bag 1 has a notch for the handle 2 and a notch 3 in the upper center.

In Fig. 2, when the mouth edge of the inner bag 1 is made into a quarter circle and the inner bag 1 is stored inside the outer bag 4, the portion 9 located at the mouth edge 8 of the outer bag 4 and the mouth edge of the outer bag 4 are shown. 8 and a portion 10 located inside the bag, and the bottom edge is cut into a convex semicircular shape parallel to the mouth edge.

In FIG. 3, both corners of the mouth edge of the inner bag 1 are cut diagonally, and when the inner bag 1 is stored inside the outer bag 4, the part 9 located at the mouth edge 8 of the outer bag 4 and the mouth edge of the outer bag 4 are shown. Part 10 inside the bag than 8
, and portions equivalent to the cut portions are left at both corners of the bottom edge parallel to the mouth edge.

In FIG. 4, when the inner bag 1 is stored in the outer bag 4 by cutting the opening edge of the inner bag 1 in a straight line upward diagonally to the left,
It has a part 9 located at the mouth edge 8 of the outer bag 4 and a part 10 located inside the bag than the mouth edge 8 of the outer bag 4, and parallel to this, the bottom edge is also cut diagonally upward to the left.

In FIG. 5, the mouth and bottom edges of the inner bag 1 are cut diagonally upward to the right in a straight line, contrary to the case in FIG. 4.

In the double bag for fruit of the present invention having the inner bag 1 having the above structure, when the inner bag 1 is stored in the outer bag 4, the portion where the inner bag 1 and the outer bag 4 overlap at the mouth or lower part is removed. Since the thickness of the paper becomes thinner, it is easier to close the opening or tear the outer bag to remove it.

Since the opening and bottom edges of the inner bag 1 are formed parallel to each other, the amount of base paper for the inner bag can be reduced compared to when the inner bag has the same shape as the outer bag. can.

As mentioned above, in the double bag for fruit of the present invention, hanging,
The outer bag removal work can be carried out efficiently, the base paper is saved, and in particular, the inner bag can move within the outer bag because the total length and width of the inner bag are approximately the same as the total length and width of the outer bag. If so, the inner bag will pop out from the rim of the outer bag, so
By positioning the inner bag so that it does not protrude from the edge of the outer bag, the inner bag does not move freely within the outer bag.
Therefore, there is no need to perform the troublesome bag-making process of gluing the inner bag to the outer bag.Moreover, since the mouth and bottom edges of the inner bag are formed parallel to each other, a single cutting blade can be used to easily shape the bottom of the inner bag. This has the effect of reducing costs.
